The Atom was a progression of the MOS Technology 6502-based machines that the company had been making from 1979. The Atom was a cut-down Acorn System 3 without a disk drive but with an integral keyboard and cassette tape interface, sold in either kit or complete form. In 1980 it was priced between £120 in kit form, £170 (equivalent to £776 in 2021) ready assembled, to over £200 for the fully expanded version with 12 KB of RAM and the floating-point extension ROM.
